Hi,

Customer can refer TWR-K70F120M board about hardware design how to connect K61 with DDR2 SDRAM device.

The TWR-K70F120 board hardware design resource package (includes schematics, layout, BOM info) could be downloaded from below link:

Kinetis K70 120 MHz Tower System Module|Freescale

Freescale also provides Kinetis DDR controller initialization tool could be downloaded from below link:

KINETIS_K70_DDR_INIT (Kinetis K70 DDR memory initialization tool):
